Bidens ferulifolia plant named ‘Bidantis’

ABSTRACT

A distinct cultivar of Bidens plant named &#39;Bidantis&#39; which is particularly distinguished by its vigorous character, upright (bit trailing) plant habit, dark green foliage and golden yellow inflorescences. The new cultivar can perfectly be used in mixed hanging baskets.

Latin name of the genus and species of the plant claimed: Bidens ferulifolia.

Varietal denomination: ‘Bidantis’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new distinct cultivar of Bidens, botanically known as Bidens ferulifolia, native to South USA and Mexico. The new cultivar is propagated by cuttings resulting from a seedling from Bidens ferulifolia cv. ‘BQ001’ (not patented). This new plant is an annual. The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, The Netherlands. The objective of the breeding program was to develop an intermediate between the compact Bidens varieties and the very vigorous trailing Bidens varieties. As a result of an open pollination of Bidens ferulifolium BQ001 (unpatented and commercialised in Europe) the present cultivar was created in 1999 in Enkhuizen. ‘Bidantis’ was asexually reproduced by cuttings for 3 years now and trialled under different conditions in Europe on trial. The instant plant reproduces true to type in successive generations of asexual reproduction.

DESCRIPTION OF THE DRAWING

This new Bidens plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Bidens plant. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 13 weeks old plants, grown in hanging baskets in Enkhuizen, The Netherlands with day temperatures ranging from 16 and 20 degrees C., and night temperatures ranging from 12 to 14 degrees C. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
